/**
 * Title 章节标题
 * @description 章节标题，通常用于记录页面标题，使用当前组件，uni-app 如果开启统计，将会自动统计页面标题
 * @tutorial https://ext.dcloud.net.cn/plugin?id=1066
 * @property {String} type = [h1|h2|h3|h4|h5] 标题类型
 *  @value h1 一级标题
 *  @value h2 二级标题
 *  @value h3 三级标题
 *  @value h4 四级标题
 *  @value h5 五级标题
 * @property {String} title 章节标题内容
 * @property {String} align = [left|center|right] 对齐方式
 *  @value left 做对齐
 *  @value center 居中对齐
 *  @value right 右对齐
 * @property {String} color 字体颜色
 * @property {Boolean} stat = [true|false] 是否开启统计功能呢，如不填写type值，默认为开启，填写 type 属性，默认为关闭
